FW, the proposals can be interpreted as maximising performance without changing the existing margins required by certification. In some, most instances the take off will have greater altitude margins because the control seeks the best speed-pitch combination for the thrust available.
'The best pilot, best accuracy, consistency - everyday'
There is no expectation for pilot intervention. By using the exiting autoflight system the existing protections can be used, i.e. as for autoland or FD.
A V1 engine failure might involve rudder compensation; some aircraft have this, does Embraer.
Additionally, with auto control of pitch - speed (the basis of the optimisation) the piloting workload is significantly reduced; no need for manual wiggle corrections to match attitude to speed.
